Charbagh or Chahar Bagh (Persian: چهارباغ, chahār bāgh, "Four Bāghs") is a Persian-style garden layout. The quadrilateral garden is divided by walkways or flowing water into four smaller parts. In Persian, "Chār" means 'four' and "bāgh" means 'garden'.
One of the hallmarks of Persian gardens is the four-part garden laid out with axial paths that intersect at the garden's centre. This highly structured geometrical scheme, called the chahar bagh, became a powerful metaphor for the organization and domestication of the landscape, itself a symbol of political territory.
The Chahrbagh-e Abbasi (or Charbagh Avenue) in Isfahan, Iran, built by Shah Abbas the Great in 1596, and the garden of the Taj Mahal in India are the most famous examples of this style. In the Charbagh at the Taj Mahal, each of the four parts contains sixteen flower beds.
Chahrbagh originated from the time of Achaemenid Persia. Greek historians, such as Herodotus and Xenophon, give extensive accounts of Cyrus the Great's palatial city of Pasargadae and his four-gardens.
In India, the Char Bagh concept in imperial mausoleums is seen in Humayun's Tomb in Delhi in a monumental scale. Humayan's father was the Central Asian Conqueror Babur who succeeded in laying the basis for the Mughal dynasty in the Indian Subcontinent and became the first Mughal emperor. The tradition of paradise garden originated among the Mughals, originally from Central Asia, which is found at Babur's tomb, Bagh-e Babur, in Kabul.
